Chaise Longue: Dual-Level Seats Eye Premium Sky Travel

A revived Chaise Longue dual-level airplane seat concept moves from a college project into a working mock-up that envisions a top and bottom seating level by removing the overhead cabin to improve space and privacy. The latest version adds larger seat pitch, better privacy panels, and potential middle-seat lie-flat options, with a shift toward premium economy rather than economy. While aviation insiders show interest and retrofitting challenges and regulatory hurdles loom, no airlines have committed to production yet.
